Stable Temperature Control And Safe And Reliable Help Battery Efficient Operation - The Preferred Material For Extending Battery Life: Phase Change Materials For 45℃ Batteries

Product Introduction:

1. 45℃ battery special phase change material is a kind of functional material specially designed and developed for battery thermal management system. It is mainly composed of substances with specific phase transition temperature properties, and its core phase transition temperature is precisely set at about 45°C.
2. At room temperature, it exhibits a specific physical form and chemical stability. When the battery generates heat during charging and discharging, causing the temperature to rise to 45°C, the phase change material will rapidly undergo phase change.
3. For example, from solid to liquid, in the process of absorbing a lot of heat, so as to effectively prevent the battery temperature from further climbing, to avoid the battery due to overheating and performance decline, shorten life and even cause serious problems such as thermal runaway.
4. When the temperature of the battery is reduced, the phase change material in the liquid state will reverse phase change back to the solid state, releasing the heat stored before, playing a certain role of insulation, so that the battery is maintained in a more suitable working temperature range, reducing the adverse effects of low temperature caused by the battery charging and discharging efficiency, internal resistance increase and so on.

Product advantages:
1. Precise temperature control

• It can accurately absorb or release heat at about 45°C, so that the battery is always kept in a relatively stable operating temperature range, and avoid adverse effects on battery performance due to too high or too low temperature.
• For example, high temperature leads to shortened battery life and reduced performance, and low temperature reduces battery charging and discharging efficiency, effectively extending the service life of the battery.

2. Efficient energy storage

• During the phase transition process, it can absorb or release a large amount of latent heat, and the energy storage density is large. Compared with traditional sensible heat storage materials, it can store more heat under the same volume or mass, so as to achieve efficient heat storage and release, which helps to improve energy utilization efficiency and reduce energy waste.

3. High security

• When the battery temperature reaches 45°C, the phase change material will actively absorb the heat of the battery cell, preventing the battery temperature from further rising, reducing the risk of thermal runaway of the battery.
• When the battery damage temperature is momentarily too high, the phase change material can also absorb a lot of heat into liquid state, prevent the battery from fire, explosion and other accidents, and provide a more reliable safety guarantee for the use of the battery.

4. Passive thermal management

• No additional power components or complex control system to drive its work, relying on its own phase change characteristics can achieve the adjustment of battery temperature, system structure is simple, low cost, and reliable operation, reducing the complexity and cost of battery thermal management system.

5. Improve battery performance consistency

• The temperature of each cell in the battery string is more uniform, reducing the temperature difference, improving the performance consistency of the battery string, avoiding the overall battery string performance degradation caused by the temperature inconsistency of the battery string, and improving the charging and discharging efficiency and output power of the battery string.

Product application scenarios:
1. Thermal management of power battery

• In the power battery pack of electric vehicles, 45℃ battery special phase change materials can be used to maintain the operating temperature of the battery.
• When the battery generates heat in the charge and discharge process, and the temperature rises to 45°C, the phase change material undergoes a phase change to absorb heat, prevent the battery from overheating, avoid problems such as shortened battery life, reduced performance and thermal runaway caused by high temperature, extend the service life of the battery, and improve the safety and reliability of electric vehicles.

2. Power grid energy storage

• In the power grid energy storage system, a large number of energy storage batteries need to work stably under different environmental conditions.
• Special phase change materials for 45℃ batteries can effectively adjust the temperature of the battery, ensure that the battery maintains good performance during the charging and discharging process, improve the efficiency and reliability of the power grid energy storage system, enhance the stability and flexibility of the power grid, and promote the large-scale access and consumption of renewable energy.

3. Space vehicle power supply system

• Battery is one of the important power sources in space vehicle.
• Phase change materials can provide effective temperature control for space batteries, prevent batteries from being damaged by extreme temperature changes in space, ensure the stable performance of batteries during launch and in-orbit operation, and ensure the smooth progress of space missions.
